Abstract: A USB Type-C/Power Delivery controller chip includes a first pin for receiving a first voltage, a second pin for receiving a second voltage, and a third pin for coupling to the CC pin of a USB connector. The USB controller chip includes a VCONN power supply circuit having a blocking field effect transistor (BFET) coupled in series with a hot-swap field FET (HSFET) between the first and third pins, and first and second Zener diodes coupled anode-to-anode between the HSFET's source and gate. A cable detection circuit includes a BFET coupled between the second and third pins, and a Zener diode coupled between the BFET's gate and a lower rail. A power delivery physical layer circuit includes a receiver and a transmitter, each coupled to the third pin through a respective BFET, the respective BFETs each having a Zener diode coupled between respective gates and the lower rail.

Abstract: An electronic device having multiple power output circuits that individually include a switch control input, a bypass control input, an output transistor and an output control circuit that includes an RC circuit with a resistor and a capacitor coupled to the output transistor gate and a bypass switch in parallel with the RC circuit resistor. The electronic device includes a controller that selects one of the power output circuits for a given power transfer cycle, closes the bypass switch to bypass the resistor of the selected power output circuit and turns the output transistor of the selected power output circuit on to transfer current from the inductor to a load of the selected power output circuit.

Abstract: In described examples, a sawtooth waveform generator generates a sawtooth waveform having a first rise time. A comb waveform circuit has a power terminal coupled to receive the sawtooth waveform from an output of the sawtooth waveform generator. The comb waveform circuit generates a comb waveform in response to the sawtooth waveform. The comb waveform has a second rise time that is faster than the first rise time.

Abstract: A switch-mode power supply includes a DC-DC converter and metering circuitry that is coupled to the DC-DC converter. The metering circuitry includes scaling circuitry, a current source, a capacitor, switching circuitry, and a comparator. The scaling circuitry is configured to generate a reference current scaled to be a predetermined fraction of a peak current flowing in an inductor of the DC-DC converter. The current source is configured to output a first current that is one-half of the reference current. The capacitor is coupled to the current source. The switching circuitry is configured to switchably connect the current source to the capacitor. The comparator is coupled to the capacitor. The comparator is configured to generate a signal indicating that a voltage across the capacitor exceeds a threshold voltage.
